Three-dimensional micro tomography analysis of electrical resistivity (Micro-ERT 3D) can detail soil moisture content and can monitor areas where uptake occurs near a plant’s root system.
This patent improves the 3D Micro-ERT to achieve high levels of measurement accuracy.
In fact, the present invention allows to obtain a resolution such as to monitor the evolution in space and time of the water content of the subsoil and the relative root activity of the plant, thus optimizing the use of the irrigation resource.
The proposed apparatus is also watertight and stainless and can be left in situ for long periods allowing the operator to carry out accurate time-lapse monitoring, otherwise strongly limited by non-homogeneous acquisition conditions.

  • RAPID-AFM1 – Rapid detection of Aflatoxin M1 in milk

    The present invention relates to a method and a device useful for directly and rapidly quantifying the presence in milk of Aflatoxin M1, a carcinogenic mycotoxin deriving from Aflatoxin B1. In particular conditions of humidity or high temperatures, some vegetable[...]

  • Characterization of complex sugar mixtures

    To guarantee the quality and authenticity of foods such as honey, fruit juices or nectars, it is important to have detailed information on the type and quantity of sugars they contain. The more common methods used to quantify sugars and[...]

  • Vaccine efficacy prediction in poultry farming

    The method described in this patent can predict the efficacy of vaccines against avian infectious bronchitis virus (IBV), without the use of experimental infections. Currently, the control of IBV in poultry farming is based on the use of attenuated vaccines.[...]
